Java Forum / General / November 2005SimpleORB now available for VW Smalltalk, java and C#
SimpleORB is a simple Object Request Broker for VisualWorks Smalltalk, java and C#. It uses a simple but powerful serialization library for data marshalling. Because this is not a CORBA server, it is quite small (about 150kByte for all languages together). There exists a Wikipedia entry with a simple Helloworld application: http://en.wikipedia.org/wiki/SimpleORB Performance is ca. 500 calls/s with java client and Smalltalk server. 1600 calls/s with java client and java server and 1660 calls/s with C# client and server (all on 1.8 GHz Athlon).

SignatureCanadian Mind Products, Roedy Green. http://mindprod.com Java custom programming, consulting and coaching. An Object Request Broker (ORB) can be used to create a distributed (often called client/server) application. An ORB provides the means to perform method calls from one process to another (potentially on another machine somewhere in the network). This means that a remote object can be called, with all call parameters being transmitted over the network and the results being transmitted back to the calling process. This is often called "marshalling" or "serialization". Popular ORBs are the CORBA-type systems, DCOM or RMI. (Hopefully this explanation addresses the previous posting...) For a definition of "ORB", wikipedia might be consulted: http://en.wikipedia.org/wiki/Object_Request_Broker Thanks. You might like to prefix your subject with ANN: for announcing. Some people like to filter these out if they are spam haters. Personally I like to see announcements of useful things.

And why would someone want your ORB in preference to RMI? What is its niche? SignatureCanadian Mind Products, Roedy Green. http://mindprod.com Java custom programming, consulting and coaching. Ok, I have to improve in the marketing department :-)) SimpleORB is -cross-plaform, cross language (like CORBA, unlike DCOM and RMI) -simple (no IDL, no IDL compiler runs) -small (no stubs, no skeletons, small runtime lib (150kBytes)) -powerful (arbitrary object graphs marshalled, like RMI, unlike CORBA) -fast (unlike SOAP) -free Maybe some of the RMI expets can post some performance data (I am too tired to create an RMI benchmark this night...) It's an interesting product and can be very useful, but you should be careful becouse SimpleORB is not CORBA-compliant. As I stated, being not CORBA-compliant is a virtue- no need for IDL files, no lengthy IDL compiler runs, arbitrary object graphs (not just trees). Just ran a Helloworld program in RMI: Performance (calls/second) of RMI is about the same as with SimpleORB. Of course, all these qualities are a value added, but in a EAI project is important to know that is not interopetable with CORBA systems.
